An Israeli nationalist group has urged Bar Refaeli to ditch boyfriend Leonardo DiCaprio – so she can settle down with a Jewish husband.

The supermodel, who has been dating the “Titanic” star on and off since 2005, was forced to deny rumors she was engaged to DiCaprio earlier this month after she was spotted wearing a ring on her wedding finger.

She told reporters the couple had no plans to marry – but her comments failed to stop an Israeli politician from warning her to stay away from the actor.

Baruch Marzel’s letter, sent on behalf of the Lehava organization, read: “It is not by chance that you were born Jewish. Your grandmother and her grandmother did not dream that one of their descendants would one day remove the family’s future generations from the Jewish people. Assimilation has forever been one of the enemies of the Jewish people.”

Marzel adds that he “has nothing against Mr DiCaprio, who I have no doubt is a talented actor,” before concluding: “Come to your senses, look forward and back too – and not only the present. Don’t marry Leonardo DiCaprio, don’t harm the future generations.”

JDH/JCP/WENN.com Alec Baldwin is jealous of Leonardo DiCaprio – he wishes his movie career was as successful as the “Titanic” star’s. Baldwin, who appeared alongside DiCaprio in Martin Scorsese films …

He says, “I just feel like the kind of work I would love to have done would have been more like when Leo did ‘The Aviator.’ I love Leo. I adore him and envy him.

“I remember being there with him and thinking that he has youth, he has talent, he has opportunity, he has everything in the business. I thought, ‘What a great gift – to have that convergence of all your abilities and the opportunity to work with Marty Scorsese, and the scripts and the budgets and everything.'”

Leonardo DiCaprio’s girlfriend, Bar Refaeli, has brushed off rumors the Hollywood actor recently proposed, insisting the gold band she’s wearing on her left hand is not an engagement ring.

The actor was rumored to have popped the question to the Israeli supermodel over the Valentine’s Day weekend after she was seen sporting a new piece of jewelry.

But when questioned about the engagement rumors, Refaeli is adamant the couple has no plans to marry.

She tells E! Online, “No, there wasn’t (a proposal). Let me explain: These rings — which are beautiful and made by a friend of mine — won’t fit any other finger except this one. I’m 24 and there’s still time (for marriage). I’m in no hurry. I’m happy with where I am.”

Leonardo DiCaprio has distanced himself from reports he’s set to portray Frank Sinatra in director Martin Scorsese’s upcoming biopic of the late entertainer.

The “Raging Bull” filmmaker is set to bring Ol’ Blue Eyes’ life story to the big screen in forthcoming film “Sinatra” – and DiCaprio, who has been Scorsese’s leading man four times to date, was rumored to be stepping into the “My Way” singer’s shoes.

But the “Titanic” hunk is baffled by the reports – because he has not been approached to star in the film.

He tells New York Magazine, “There are no plans to do that (portray Sinatra) as of yet.”

Scorsese admits the movie has been stalled as screenwriters work on the script, but he insists whoever ends up playing the Rat Pack legend on the big screen will not be showing off their vocal talents – because the singer’s hits are classics.

The director tells the Hollywood Reporter’s columnist Roger Friedman, “With those records, Frank will do the singing. But we’re waiting for a finished script.”

Leonardo DiCaprio understands the struggle some Hollywood legends face when their career start to wane, insisting it’s easy for stars to become detached from reality.

The actor has been a mainstay of the movie industry since his critically acclaimed turn in “What’s Eating Gilbert Grape” at age 19.

He became one of Hollywood’s hottest leading men after starring in James Cameron’s hugely successful “Titanic,” and has proved a hit at the box office ever since.

But DiCaprio doesn’t take his popularity for granted, insisting he can see how stars become “nuts” after falling for their own hype.

He tells “Access Hollywood,” “Just because you’ve done a good performance once, doesn’t mean you’re always going to be good. That’s why some of the greatest actors in the world have gone a little bit nuts. They’re saying to themselves, ‘What happened? You used to love me?’

“It’s an easy trap to fall into. You just have to realize that when you’re hot, you’re hot, and when you’re not, you’re not.”

German newspaper Bild sparked fresh speculation of an impending wedding after publishing photos of Refaeli wearing a gold band on her ring finger on Monday.

The tabloid claimed DiCaprio had proposed to the Israeli beauty on Valentine’s Day after spending the romantic date at the Berlin International Film Festival, where the actor’s new movie “Shutter Island” was premiered.

But sources close to the “Titanic” star have dismissed reports the on/off couple is set to exchange vows.

One insider tells UsMagazine.com the claims are “not true”.

It’s not the first time the stars have been rumored to be heading to the altar – last March, the couple was alleged to have cemented its four-year romance with a low-key wedding. The reports were subsequently denied.

Leonardo DiCaprio regrets failing to introduce himself to River Phoenix at a Halloween party – because just hours after their chance encounter the young actor lost his life outside a Los Angeles nightclub.

DiCaprio was at the beginning of his Hollywood career when he spied his longtime hero Phoenix at a party on October 31, 1993.

The “Titanic” star, who was 18 at the time, was desperate to corner his idol for a chat but didn’t have time to approach Phoenix before he left the party.

And DiCaprio will always remember the missed opportunity, because 23-year-old Phoenix collapsed and died from a drug overdose outside the Viper Room just hours later.

He tells Esquire magazine, “When I was eighteen, River Phoenix was far and away my hero. Think of all those early great performances – My Own Private Idaho, Stand by Me. I always wanted to meet him. One night, I was at this Halloween party, and he passed me. He was beyond pale – he looked white. Before I got a chance to say hello, he was gone, driving off to the Viper Room, where he fell over and died.”

The actor plays a detective trying to solve a missing persons mystery in an asylum in the new Martin Scorsese movie, and decided to study the mentally ill to perfect his role.

But admits he maybe took his homework a little too far: “There was a tremendous amount of research done involving the entrapments of mental illness and the suffering that people go through, so it led me to watch a lot of different documentaries on mental illness.

“For a few weeks there, it was some of the most hardcore film experiences I’ve ever had. It was like reliving trauma in a way. It was pretty intense.”

And the intensity didn’t stop when filming began.

DiCaprio tells WENN, “We were surrounded by it (mental illness) every day. We were surrounded by dilapidated walls of an old mental institution. We had somebody there who was guiding us through the history of mental illness, the pathways of treating it and the different forms of treatment.”

The actor met the blond in London last month during a break from filming sci-fi movie “Inception” and promptly whisked her and a group of friends away for a sunshine holiday in Ibiza, Spain, reports Britain’s The Sun newspaper.

And the star is seemingly smitten with the 23-year-old, enjoying a number of nights out in the British capital with her over the last week.

A source tells the publication, “It’s very early days but they can’t keep their hands off each other. When Leo first arrived (in London) there were swarms of girls all over him but now he only has eyes for Anne.”
